摘要
Abstract
Balance in the installation of wind tunnel model of the processing error tend to produce the assembly stress .The interference of element output value affects the accuracy of measurement .In view of this phenome-non ,using the finite element simulation method ,the influence on measurement results of different balance’s fixed end length on the assembly stress is investigated based on keeping the total length invariant .The results show that :as long as the assembly stress exists ,balance measurement results will be influenced .But the length of fixed end has no obvious effect on this .Therefore ,methods of improving the measurement accuracy is to take actions to reduce the additional installation stress in wind tunnel balance design or experiment instead of chan-ging fixed end length of balance .关键词
